Benefits of technology

[0012]The method of the invention can be used to bond windows into structures such as automobiles and buildings. The method allows preparing and bonding of windows without interfering with the bonding of the adhesive to the glass or ceramic enamel frit surface. The method further enhances the bonding of the adhesive to the glass or ceramic enamel frit. In certain circumstances the method allows the adhesive to bond to the surface of the glass or the ceramic enamel frit without the need for one or both of the cleaning or priming steps. The method of the invention does not harm the glass or the ceramic enamel frit surface on the window.

Problems solved by technology

These contaminants can interfere with the bond of the adhesive used to bond the glass into a window frame.
The problem is that the abrasive pad can damage the ceramic enamel frit.

specific embodiments of invention

[0038]The following examples are included for illustrative purposes only and are not intended to limit the scope of the invention. Unless otherwise stated, all parts and percentages are by weight.

[0039]The efficiency of an alumina containing composition comprising 39.1 weight percent water, 49.5 weight percent alumina, 10.0 weight percent white mineral oil (petroleum), 0.9 weight percent sodium lauryl sulphate, 0.4 weight percent hydroxyethylcellulose, 0.03 weight percent fatty alcohol ethoxylated and 0.09 weight percent orange fragrance for enhancing the bonding of adhesives to glass surfaces is determined by quick knife (peel) tests on silicone contaminated enamel frits in comparison to alternative treatment processes.

Preparation of Samples for Testing

[0040]Silicone contaminated ceramic frits are treated with the alumina containing composition and / or cleaned with different cleaners, specifically BETACLEAN™ 3300 glass cleaner and / or BETACLEAN™ 3350 glass cleaner as described herein...

Abstract

In one embodiment, the invention is a method comprising contacting a composition comprising i) alumina particles having a particle size of about 1 to about 40 microns and a Mohs hardness of about 9.0 to about 9.5; ii) one or more alkyl sulphates; iii) one or more thickeners; and iv) water with the surface of glass or a ceramic frit disposed on the surface of glass. The contacting can be performed by applying the composition to the surface of the glass or the ceramic frit using an application apparatus. In one embodiment, the composition further comprises a lubricant. In another embodiment, the composition further comprises one or more ethoxylated alcohols. In another embodiment, the composition further comprises one or more fragrances.

Description

CLAIM OF BENEFIT OF FILING DATE[0001]The present application claims the benefit of the filing date of U.S. Application Ser. No. 60 / 932,243, filed May 30, 2007, which is hereby incorporated by reference for all purposes.FIELD OF INVENTION[0002]The invention relates to a method of preparing a glass surface or a ceramic enamel frit on the surface of glass for adhesive bonding utilizing an alumina containing composition. The invention further relates to a method of bonding glass into a window frame wherein the glass or the ceramic enamel frit disposed on the glass is treated with an alumina containing composition prior to contacting the adhesive with the glass or ceramic enamel frit.BACKGROUND OF INVENTION[0003]Windows made from glass are often delivered with contaminants on the surface of the glass, such as silicone based materials. These contaminants can interfere with the bond of the adhesive used to bond the glass into a window frame. Glass windows often have disposed on the periphe...
